Métrologie Quantique

The team, tiny as it is, made the trek out to the beautiful, scenic, and altogether inspiring Calern site of the Observatoire to participate in a frequency comparison campaign with Refimeve in mid-January.

We arrived at the building Métrologie Optimus (MéO), where the local Refimeve downlink is available from a Exail / iXblue / MuQuans repeating station. We compared this signal to the local passive and active masers (T4 Science) via an optical frequency comb, a Rubicomb by Vescent, brought for demonstration by Baptiste Callendret of Opton Laser. It came out the box, onto the table, and we were in operation within ten minutes or so... 

Eleonora Polini and I were joined by colleagues stationed at Calern, Duy-Ha Phung and Clément Courde, as well as Olivier Alibart and Nicolas Forget of INPHYNI - we can not claim we were lacking in local expertise! Plenty of data was taken, which is the furthest station in l'hexagone from the source at the Observatoire de Paris - analyse en cours! Stay tuned!

A successful and expanding team at the Institut de Chimie de Nice had to get rid of a relatively new optical table to make space for their new and upcoming experimental work employing Rose-Krieger profiles (check out the team here, thank you Conny!). 

Naturally, we made a few phone calls, and the expert logistics team of the lab and OCA shuffled the table from Valrose, up Mont Gros, and into the Astrographe...

Such work is impossible without teamwork. We have to thank C. Capriani, M. Pisani, and M. Merzougui for their expert handling and patience uninstalling, loading, transporting, and reinstalling the table. All fingers accounted for...

After 6 months of renovation that maintains the historical visage of the building, the Astrographe is now the new home of the Équipe Métrologie Quantique!

Our recent work Optically dressed three-level coherence in neutral bosonic alkaline-earth-like species [Physical Review Research 6 (4), 043268 (2024)] is being presented in poster format by the lead author Paul Robert at ICOLS 2025 today on the scenic island of Elba just off the coast of Tuscany in Italy. See his thesis on TEL Archive for more details - great job Paul !

A new research line has been started at ARTEMIS UMR7250, expanding the experimental program at the Observatoire de la Côte d'Azur to include quantum metrology and precision measurement, bringing quantum technology to Mont Gros ! 

A new experiment is being financed and built - we will be looking for interns, master students, and doctoral students in the coming years. Feel free to drop us a line via the contact form for all inquires.
